Windows/Process.inc: Fix for +Asserts. &Buf[0] is not guaranteed if size is zero.<br></blockquote><div><br></div><div>This is unsatisfying.  We shouldn't have to zero the memory after allocating it.  Is there a better way we can write this pattern?  The only thing I can think of is 'reserve(Size); push_back(L'\0')'.</div>
